Hi All, I have had my C5 for about a month, on the screen i keep gethng a message telling me to top up engine oil levels. I have done this 3 times now! I have noticed on the driveway under the engine there is 3 spots of oil. Has anyone else had this warning message come up? Where is the best place to get it look at in teesside? If anyone has any ideas that would be great. cheers mark.
